There are 2 different DisneyParks Anahiem California has Disneyland and Disneyland California Adventure. Orlando Florida is Disneyworld they have water parks and various theme parks. I am not sure of how many but they have at the very least 4.
Yes, Original Disneyland and California Adventure in Anaheim, Ca - Magic Kingdom (like Disneyland), Epcot, Hollywood Studios, and Animal Kingdom are all in Florida just outside of Orlando in Disney's own city. The parks in Florida are huge and you have to get around in a bus or car to see everything. In California, it's tiny and everything is within walking distance. In Florida, things have a very vacation resort feel - in California, it feels more like a very well done day park. Both are great to visit depending on which experience you are wanting.
